` e In the construction shown. in Fig. Qv always two adjacent Vfines are connected to forni a group, against three in Fig. 1. Thisarrangement allows a more uniform heating' of the oven walls than the consti'ucltion shown in Fig. l. The method of opera'- tion and general arrangement of parts heie shown is substantially the same as previously described, so that the same description may be read on all parts of Fig. 3 bearing the saine reference nuiuerals as before. The shape of the regulating bodies 12 in this case Adiffers slightly from the shape yshown in l, 3 and In the construction shown in Fig. 2 the regulating bodies are designed to allow a regulation of the' upper connecting passage 8, the effect obtained being the saine as before. l

For convenience of description and designation of the structural features in the claims I have adopted in the claims for such heating ilues forming uptakes for the heating gases the term primary heating flu'es, and for such heating fluesforming downtakes for the heating gases the terin secondary heating fiues. j

lVliat I claim and desire to secure by Letters Patent is l. Ina coking or gas generating oven, upright heating flues in the walls thereof consisting of primary and interposed secondary heating flues,'means for supplying gas and air to the lowerk portions of said primary heating lues in such proportions as to effect only partial combustion of the gas in these fines, connections between said primary and secondaryheating fines, regulat-ing bodies,- reinovably inserted intothe,
